title: Instant recall: a key role for effector-phenotype CD8⁺ memory T cells in immune protection.
abstract: In this issue of Immunity, Olson et al. (2013) demonstrate that circulating CD8⁺ memory T cells with an effector-like phenotype, previously thought to be mostly senescent, provide robust protection from a secondary pathogen challenge despite their poor secondary proliferative response.
